How to replace non-diagonal elements in a matrix?
如何更换一个矩阵的非对角线元素？
This paper USES a new method to determine the diagonal elements of the matrices.
对于对角线元素，本文使用了一个新的方法予以确定。
A special matrix structure was adopted, that is, each row and each column has one matrix element, and the matrix elements are on the main diagonal symmetry.
我们取特殊的矩阵结构，矩阵每行，每列都有一个矩阵元，并且矩阵元位置是关于主对角线对称的。
It is proved that the stiffness matrix of the finite element solution is a block diagonal matrix and its elements are some symmetric and block circulant submatrices.
证明了有限元求解的刚度矩阵是一个块对角阵，且其子矩阵是某种对称、块循环矩阵。
Since all elements on the primary diagonal are 1s and the dimensions are less than 2006, the graph with A2006 as its adjacency matrix is the transitive closure of the graph represented by a.
由于主对角线上的元素都是1，而且矩阵的阶小于2006，所以为a2006邻接矩阵的图就是由A表示的图的传递闭包。
Replace every element on the diagonal of an array with the sum of the elements on the current column OR row.
将每一个元素的对角线，一个阵列的总和要素对当前列或行。
Given a matrix of Mx N elements (M rows, N columns), return all elements of the matrix in diagonal order.
给定一个M行N列矩阵，用对角顺序返回矩阵的所有元素。
